6 Claims. (Cl. 226-58) This invention relates to improvements in bag means are designed for use with a vacuum cleaner emptying devices. bag having a discharge opening at its lower end One object of the invention is to provide a dewhich opening is provided with a meta-l ring I3, vice for transferring the contents of one bag to having diametrically opposite ears I4 by means 5 another and particularly for emptying vacuum of which the bag is secured to the vacuum cleaner. 5 cleaner bags which precludes all necessity of The means for attaching the cleaner bag to the touching the bag contents with the hands, and emptying device is embodied in a shell indicated which will prevent the escape of dust into the surgenerally by the numeral I5, which is provided rounding air and the accidental scattering of the with a cylindrical portion I6 which may be welded l0 bag contents upon the floor. or otherwise secured to the upper end of the l0 Another object of the invention is to provide cylinder I0.

It is to be noted in Figure 2 that the annular ilange I8 tapers slightly inwardly, thereby enabling the ring to be pressed downwardly sufficiently until it forms a close seal. To release the bag from the device the ring I3 is rotated sufficiently to effect the disengagement of the ears I4 from the clips 20, whereupon the ring I3 can be lifted out of engagement with the annular flange I8. Should particles of refuse drop from the margin of the ring I3 and fail to pass into the device they will be caught on the shoulder I1 which, as above stated, forms a concave annular pan for retaining such refuse, and thereby preventing the same from dropping upon the iloor.

When the bag I9 has been detached from the device, the latter is lifted gently from the sack 2I, thus transferring the contents of the device to the sack, which may then be disposed of as desired.

In using the improvements as above described, it is preferred that means be provided for holding the device in upright position and firmly in contact with the lower portion of the sack to prevent escape of dust around the lower edge of the member I0 and thus into the atmosphere.

Suitable holding means are illustrated, and comprise three members 22 which at their upper ends may be secured as by spot welding to the flange 23 which is formed as an integral part of the shell I5.

The flange 23 as shown is so spaced from the side wall of the device Ill that the holding members 22 will accommodate between the same and the member I0 the upper portion of the sack 2 I.

The lower ends of the holding members 22 are provided with laterally extending portions or feet 24 upon one or more of which the user may step to press the device firmly against the floor and form a dust proof seal with the paper sack during the transfer of the bag contents into the device.

It will be noted that any sack or bag which is large enough to receive the member Ill can be used with the improved device notwithstanding that they may be considerably larger than are necessary. Paper market bags are delivered to most homes several times a Week and these otherwise discarded bags can be used with the improved device, thus rendering the purchasing of special bags unnecessary.

While I have shown and described an embodiment of my improvements for the purpose of illustration, I do not wish to be restricted specifically thereto except as so limited by the appended claims.

I claim:

l. A bag emptying device comprising a cylindrical member having an opening at each end thereof and of a diameter capable of being inserted in a sack with the lower end thereof closed by the lower portion of the sack, means at the upper end of said member for removably attaching thereto the discharge end of a vacuum cleaner bag whereby the contents of the bag can be discharged into said member, the said contents being discharged through the lower end of said member into the sack upon withdrawal of said member from the sack, and foot pressable means exterior of the sack and disposed adjacent the bottom of the cylinder for holding the bottom of the latter in dust confining contact with the sack during the bag emptying operation.

2. A bag emptying device comprising a cylindrical member open at the upper and lower ends and capable of being inserted in a sack with the lower end in contact with the bottom portion of the sack, holding means spaced from the outer wall of said member for accommodating the upper portions of said sack between said means and wall whereby the lower end of said member and sack can be pressed firmly against a support to provide a seal at the lower end of said member, and means at the upper end of said member for releasably holding the discharge end of a bag to be emptied in registration with said upper open end of said member.

3. A bag emptying device comprising a cylindrical member open at the lower end and adapted to be inserted in a sack with the lower end of the member in contact with the lower portion of the sack, the upper end of said member being provided with an opening through which the contents of a bag to be emptied can be transferred to the interior of said member, means for holding the .discharge end of said bag in registration with said opening, and one or more holding means secured at the upper ends thereof adjacent the upper portion of said member and extending downwardly to adjacent the lower end of said member and being spaced from the exterior wall of the latter for accommodating therebetween the upper portion of the sack, said holding means being provided with portions by means of which the user may press said member into rm contact with the sack and the latter against a floor during the transfer of the bag contents to said member.

4. A bag emptying device for vacuum cleaner bags having a discharge opening provided with an attaching ring, said device comprising a cylindrical member open at the lower end and adapted for insertion in a disposable sack with the lower end of said member in contact with the lower portion of said sack, an annular shell secured to the upper end of said member and having an upwardly extending flange of a diameter closely fitting the interior of said ring, means adjacent said flange for releasably locking said ring thereto, said shell having a downwardly extend- .f

ing flange spaced from the side walls of said member, and a plurality of holding members secured at the upper ends thereof to said last mentioned flange and extending downwardly to adjacent the lower end of said cylindrical member and being spaced therefrom for accommodating the upper portion of the sack therebetween, said holding members being provided with lateral extensions upon one or more of which the user can step to press the lower end of said cylindrical member into sealing contact with said sack during the transfer of the contents of said bag to said member.

5. An emptying device for vacuum cleaner bags comprising a cylinder open at the bottom and insertable in a disposable sack adapted to retain the refuse upon withdrawal of said cylinder, an annular member secured to the upper end of said cylinder terminating at its inner periphery in an upstanding flange arranged for insertion into the discharge end of a bag to be emptied and having its outer margin extending downwardly in spaced relation with respect to the exterior of the cylinder, and foot-holding means secured to said margin and extending exteriorly of the sack to adjacent the base of the cylinder whereby the latter can be foot-pressed into dust confining Contact with said sack during the discharge of the bag contents into said cylinder.

6. An emptying device for vacuum cleaner bags Cil comprising a cylinder open at the bottom and arranged to be inserted in a disposable sack whereby the contents of the cylinder will be transferred to the sack upon Withdrawal of the cylinder, foot pressing means for pressing the cylinder into dust confining Contact with the bottom of the sack, said means being spaced from the exterior of said cylinder whereby the sack can be drawn upwardly around the cylin- 10 der, and an annular member' secured to the upper end of said cylinder, said member having an upstanding flange at its inner periphery arranged for dust confining contact With the discharge opening of a bag to be emptied, a depending flange at its outer periphery spaced from the exterior of said cylinder and to which said foot pressing means are secured, and an annular channel between said iianges defining a dust pan adjacent said inner flange.
